Abstract
The Makuie sheep is a fat-tailed sheep breed which can be found in the
Azerbaijan province of Iran. non-genetic parameters obtained from data
collected from 1993 to 2012 Makuie sheep research station of West Azerbaijan
province in Iran were evaluated in the present study. The non-genetic
parameters for birth weight, weaning weight (3 months), 6-month, 9-month and
yearling weight traits were estimated based on 19 years of data using SAS
software. Least squares means were 4.11? 0.88, 21.50?3.50, 27.18?3.53,
28.57?4.44 and 34.21?3.88 kg for weight at birth, 3, 6, 9 and 12 month,
respectively. The birth year had a significant effect on all traits while the
effect of birth type significantly affected all traits (p<0.05). The lamb's
sex had a significant effect on all traits (p<0.05). The effect of dam?s age
had a significant effect on all traits except 9- month (p<0.05). Results
showed that non- genetic factors have an important role in expressing of
genetic potential in the lambs.
